We have our own very strict standards for supplier selection and a rigorous validation process to ensure potential suppliers meet these requirements. We always check the history of our suppliers and personally visit almost all of them to verify their 9001/GMP standards. We run routine tests of all of our batches of e-liquid to ensure that the quality meets our standards. All quality control is done in our own fully-equipped laboratory.
